Amazon Aurora PostgreSQL-Compatible Edition adds support for the pg_bigm extension. pg_bigm extension provides full text search capability in PostgreSQL. This extension allows a user to create 2-gram (bigram) index for faster full text search.
Characters that comprise text are represented as numbers to computers. Languages such as English, French, Russian, and Hebrew use character sets of fewer than 256 characters that can be encoded in a single byte. Languages with many characters (e.g., Japanese) require more numbers, which are represented by multi-byte encoding. pg_bigm allows you to create a 2-gram (bigram) index for faster full text search of text encoded with multi-byte characters.
Please review the Aurora documentation to learn more. You can view a list of all PostgreSQL extensions supported on RDS on the Amazon Web Services User Guide.
